After many years of skiing, I finally broke down and purchased tuning gear this off-season. I still let my local shop setup the edge angles on my new skis and give the old ones a "sharpen and wax" tune-up prior to my first day.
My first ski day involved the usual thin-cover spots and icy conditions (this is the Northeast) so my shop-pristine edges were no longer so pristine. I had watched lots of YouTube videos and had received some hands-on coaching by @cgeib during some of my recent trips out to Colorado, so I went ahead and waxed 'em up and took a diamond stone to the edges to knock the burrs off, etc.
I was pretty curious as to how my skis would behave on New England's trademark hardpack... As soon as I clicked in and start skating for the lift I knew the wax job was more then good enough. And as soon as I made my first turn I realized I hadn't messed up my edges in some fashion either.
Skied on them all weekend. Put them back on the shop bench this morning, knocked the burrs off again... Wax them back up at some point this week. Repeat. I'll easily make back my investment in tuning gear sometime this season.
Just wanted to give a shout out of thanks to all the regular posters in this forum who have put out so much helpful information in terms of demystifying the process!
